Bus Resource busy panic

[Barney Cordoba]

I have a situation that results in a panic in 8 that runs happily in 7.
Its a bus_alloc_resource of type SYS_RES_MEMORY that is used by 2
separate devices. 

I see there is an RF_SHAREABLE flag. That flag hadn't been set, but is there
something in 8 that now requires it?

As a side question, should a bus_alloc_resource call panic the system just
because the resource is busy?
